The Value attribute is the opposite of the Image attribute:

declare
   The_Value : constant Integer := Integer'Value ("123");
begin

You can also instantiate package Ada.Text_IO.Integer_IO, which exports a
subprogram Get to read a value from a string.

declare
   The_Value : Integer;
   Last : Positive;
begin
   Ada.Integer_Text_IO.Get (From => "123", Item => The_Value, Last => Last);
